The reliability of technological systems with high energy efficiency in residential buildings

The importance of reliability parameters increases when those requirements the system must fulfill change. Anyway these systems have a safe impact on the costs of exertion and management. Such costs will be added to the ones produced by the energy consumption of the plant. By using the word costs we mean: installation and management costs; a high efficient and reliable plant usually has high installation costs and low exertion costs. The opposite situation occurs in highly maintainable plants only under specific circumstances.
